Digital signage is a form of electronic display that is installed in public spaces. Digital signs are typically used to entertain, inform or advertise (together known as "adfotainment"). Major benefits of digital signs over traditional static signs are that the content can be exchanged more easily, animations can be shown and the signs can adapt to the context and audience, even interactively. Digital signage advertising is a form of out-of-home advertising in which content and messages are displayed on digital signs, typically with the goal of delivering targeted messages to specific locations at specific times. Digital signage offers superior return on investment compared to traditional printed signs
